How large a gathering is too large during the coronavirus pandemic?
Mathematical models explain why large gatherings are especially dangerous in an epidemic, and identify how large is too large.
- Health & Medicine
How coronavirus control measures could affect its global death toll
Slowing the virus’ spread will save millions of lives, but differences among countries could vary the pandemic’s toll in different places.
- Anthropology
Lucy’s species heralded the rise of long childhoods in hominids
Australopithecus afarensis had prolonged brain growth before the Homo genus appeared, but it still resulted in brains with chimplike neural structure.
- Anthropology
This 300,000-year-old skull may be from an African ‘ghost’ population
The age of the mysterious Broken Hill fossil suggests it came from a hominid that lived around the same time as both Homo sapiens and H. naledi.
- Animals
A cat appears to have caught the coronavirus, but it’s complicated
While a cat in Belgium seems to be the first feline infected with SARS-CoV-2, it’s still unclear how susceptible pets are to the disease.
- Health & Medicine
Social distancing comes with psychological fallout
Keeping people apart can help slow the new coronavirus’ spread. But such social distancing may cause or worsen mental health problems.
- Health & Medicine
How antibody tests work and could help fight the coronavirus
Coronavirus antibody tests look for signs in the blood that someone has had an infection and recovered, and could take only a finger prick.
- Health & Medicine
Face mask shortages have sparked creative solutions. Will they work?
Homemade masks, reusing masks and even scuba gear are some of the ideas for dealing with health care workers’ lack of supplies during the COVID-19 pandemic.
- Health & Medicine
There’s no evidence the coronavirus jumped from pangolins to people
Pangolins captured in anti-smuggling activities in southern China were found to harbor viruses related to the new coronavirus.
